G2 adapter for Zebra F-701

thingiverse

I wanted to upgrade the gel ink capacity of my Zebra F-701 beyond what's possible with Hi Tec C Slim Knock refills, so I designed this adapter piece for a Park G2 style refill instead. To use it, you'll first need to remove the knock bit from the G2 and then trim it down by approximately 7/16 inch. I opted for a Schneider refill due to its plastic construction, although an Itoya would likely work just as well. This model is scaled in inches; if necessary, adjust by multiplying by 2540% to ensure accuracy.
